Roller Coasters When a roller coaster descends at high speeds, the force exerted on a rider’s body by the roller coaster becomes less than that of gravity, producing a sensation of weightlessness. Then when the roller coaster hits the bottom and either shoots up or turns sharply, a g-force is exerted on the rider’s body for a fraction of a second. This g-force can be stronger than the one felt by astronauts during a space shuttle launch.
For Exercises 63-66, refer to the bar graphs, which display the top speeds and maximum drops
for some of the most popular roller coaster rides.
How much greater is the maximum drop of Superman: Escape from Krypton than that of Intimidator 305?

- Travel Time You are driving on a Canadian freeway to a town that is 500 kilometers from your home. After 30 minutes, you pass a freeway exit that you know is 50 kilometers from your home. Assuming that you continue at the same constant speed, how long does the entire trip take?arrow_forwardThe Skydiver Again When a skydiver jumps from an airplane, her downward velocity, n feet per second, before she opens her parachute is given by = 176 1 0.834t, where t is the number of seconds that have elapsed since she jumped from the airplane. We found earlier that the terminal velocity for the skydiver is 176 feet per second. How long does it take for her to reach 90 of terminal velocity?arrow_forwardComputer Virus The number V of computers infected by a virus increases according to the model Vt=100e4.6052t, where t is the time in hours. Find the number of computers infected after (a) 1 hour, (b) 1.5 hours, and (c) 2 hours.arrow_forward

At what time do they pass each other on the road?arrow_forwardFalling with a Parachute If an average-sized man with parachute jumps an airplane, he will fall 12.50.2t 1 20t feet in t seconds. How long will it take him to fall 140 feet?arrow_forwardAirplane Speed A man flies a small airplane from Fargo to Bismarck. North Dakota-a distance of 180 mi. Because is flying into a headwind, the trip takes him 2 h. On way back, the wind is still blowing at the same speed, so the return trip takes only 1h 12 min. What is his speed in still air, and how fast is the wind blowing?arrow_forward
